King Charles hailed the work of the Commonwealth in bringing countries together as he and Britain's senior royals gathered at London's Westminster Abbey on Monday for annual celebrations for the international organisation he leads.

Multiple members of the Royal Family have gathered at Westminster Abbey for the annual Commonwealth Day Service. The subject of this year's Commonwealth Day theme, Together We Thrive, honours the “enduring spirit of the Commonwealth family”.

At the time, Kensington Palace stated that Princess Kate was not expected to return to public duties "until after Easter," which fell on March 30. However, on March 22, she appeared in a video message, sharing that she had been undergoing chemotherapy for an undisclosed form of cancer following post-operative testing.
